In Austria Carl Christian would be Herr Habsburg
(not even a von
With his Belgian Passport he is prins/prince de Habsbourg Lorraine
no matter how Austria, Hungary, Czech Republic, France or Italy handle former titles. He can identify with this document, he can register as such, he can buy properties or request notarial or juridical acts, their descendants can pass name and titles and I can understand this is important for them.
By my understanding the only legal royal title registered somewhere for the happy fiancé is Georg Prinz von Preußen
. Whatever happens with his pretensions in Russia, he is and remains a prince of the former Royal House of Prussia. And if he has a German ID, he is registered as Prinz von Preußen
. I can not imagine any EU country, let us assume Spain, registering him as Jorge Mijįilovich prķncipe de Prusia y Romanova, gran-prķncipe de Rusia.
For Spanish authorities his father is prķncipe de Prusia
based on his German passport. But his mother is nowhere a gran-principesa de Rusia
. I assume, when she lived in Spain, his mother was registered as Dońa Marķa Vladķmirovna Romanova y Bagratión
, without any title.
